| 摘 要： | 通过分析不同生态条件下苹果繁殖器官中的附生微生物,我们从分离到的292株菌中筛选出11株苹果霉心病病原菌Alternaria alternata的拮抗菌,它们归属于芽孢杆菌属和链霉菌属。田间试验表明B25株与A32株在防治苹果霉心病方面比多菌灵更有效。这两种菌均能定植于不同于其原始生态条件下的苹果树。

| Abstract: | After analyses of the epiphytic microorgan isms in the breed organ of apple in the different ecological conditions, 11 antagonists, inhibiting Alternaria alternata (main pathogen of moldy core of apple), have been selected from 292 isolateds achieved (all epiphytic microoganisms). They mainly belong to Bacillus and Streptomyces. The results in field trials showed that B_(25) and A_(32) were more effective than Carbendazol on the control of moldy core of apple. In addition, both could be colonized the apple trees, where the ecological conditions differ from their promitive one' s |
